The Argentina-Alzheimer's disease neuroimaging initiative (Arg-ADNI) study is a longitudinal prospective cohort of 50 participants at a single institution in Buenos Aires, Argentina. Longitudinal assessments on a neuropsychological test battery were performed on 15 controls, 24 mild cognitive impairment (MCI) patients and 12 Alzheimer's disease (AD) dementia patients. In our study population, there was a high prevalence of positive AD biomarkers in the AD group, 92.3% (12/13); and a low prevalence in the normal controls, 20%; almost half (48%) of the patients diagnosed with MCI had positive amyloid detection...

OBJECTIVE: To look for the independent factors influencing the effect of cardiopulmonary resuscitation (CPR) in emergency department. METHODS: The data of patients involved in the study were retrieved from 72 network emergency hospitals in Shenzhen from September 2004 to January 2009. The data base was set up with EpiData software, according to questionnaires about cardiopulmonary arrest (CA) patients treated with CPR, and analyzed with SPSS 13.0 software. The binary Logistic regression was carried out with 8 factors which had emerged statistical significance through single factor analysis...

Patient dose determination and optimization have become more topical in recent years with the implementation of the Medical Exposures Directive into national legislation, the Ionising Radiation (Medical Exposure) Regulations. This legislation incorporates a requirement for new equipment to provide a means of displaying a measure of patient exposure and introduces the concept of diagnostic reference levels. It is normally assumed that patient dose is governed largely by patient size; however, in cardiology, where procedures are often very complex, the significance of patient size is less well understood...

By means of the light optic and electron microscopic methods atrial ganglia, myocytes, vessels of the right cardiac chambers have been studied in rats 2 days--3 weeks after application of 100 mcg of colchicine on the right nervus vagus. Certain changes of the neural fibers have been described at the area of the application. In the myocardium the microcirculatory bed, focal edema and hypoxic alterations of the myocyte ultrastructure have been revealed. In the ventrical ganglia destruction of some terminals of the preganglionar fibers, chromatolysis and vacuolization of single neurocytes, as well as intraganglionar granule-containing cells have been found...

In a combined pharmacokinetic and clinical trial the correlation was investigated between plasma levels of oxilofrine and the haemodynamic effects on eight healthy volunteers after an oral dose of 120 mg oxilofrine. Plasma levels of free oxilofrine were measured by capillary gas chromatography mass fragmentography. Cardiovascular as well as echocardiographic parameters (left ventrical extent and velocity of fractional shortening) have been measured. The results pharmacokinetically showed a marked enterohepatic reabsorption profile with a second oxilofrine plasma peak occurring in between the second and third hours...

Carbon dioxide single breath tests (SBT-CO2) were obtained during anesthesia and controlled ventilation in 42 children about to undergo thoracic surgery. The tests were obtained with a computerized system based on the Servo ventilator. The system made on-line corrections for compressed volume, apparatus deadspace, and rebreathing. Children with normal pulmonary circulation had excellent gas exchange with high PaO2 values, a mean alveolar deadspace fraction (VDalv/VTalv) of 0.10, and a gently sloping phase III of SBT-CO2...

The different nomenclatures which have been given to this malformation are discussed, defining the single ventrical as a single ventricular chamber without an interventricular septum and generally with two well defined atrioventricular orfices, although in some cases there is only one mitral-tricuspid ring. Twelve cases of single ventricle, proven by necropsic study, were examined. A new embriological-anatomical classification was proposed based on the location of the outflow tract (concordant or discordant in relation to the situs viscerae of which it is a part) and the troncoconal morphology (crossed great vessels, transposition of the great arteries, and truncus arteriosus), presenting some examples of these malformations...

1 In the anaesthetized lactating rat, the suckling of the young causes the regular release (about every 7 min) of brief pulses of oxytocin (0.5 to 1.0 mu), which each produce a single transient increase in intramammary pressure.2 The effects of several cholinoceptor antagonists were studied in relation to this natural reflex, and also the release of oxytocin evoked by the intraventricular injection of cholinomimetics.3 Reflex milk ejection was blocked by the nicotinic antagonists mecamylamine and hexamethonium, and the inhibition was dose-dependent (ED(50) of 1 mg/kg i...

Autoradiographic labelling has been employed to analyze the morphogenesis of the neostriatum. Pregnant rabbits received a single intraperitoneal injection of tritiated thymidine at different stages of gestation. Careful microscopical observation of the autoradiographs shows that cellular components of the neostriatum originate between days 15 and 18 of the intrauterine life from a layer of proliferating matrix cells that lies on the floor of the anterior part of the lateral ventrical (ganglionic eminence). From this proliferating layer, precursor cells migrate outwards to reach the developing neostriatum in a sequential fashion according to two gradients of histogenesis...
